Independent EEV driver module with RS485 protocol for the connection to a PlantVisor supervisory system.This solution is similar to EVD200 but this advanced EEV driver can operate stand-alone. This module can be managed by a digital input and the connection to PlantVisor is needed only for the first configuration.After this the driver is independent. In addition, there is the possibility to configure the 4 to 20 mA input for positionioning EEV proportionally to the input itself.
